Panduit F91ER3NB1SNM010 OS2 Single-Mode Fiber Patch Cord
The Panduit F91ER3NB1SNM010 Opti-Core fiber patch cord delivers single-mode OS2 connectivity between SC and LC/APC terminations across 10 meters of riser-rated cable. Built on 9/125µm fiber with a 1.6mm simplex jacket, this patch cord addresses short-to-medium datacenter runs, equipment cross-connects, and structured cabling horizontals where polarity management and low insertion loss matter. The yellow OFNR jacket meets NEC riser plenum requirements for vertical pathways, and the LC/APC angled physical contact connector minimizes back reflection—critical for high-speed coherent optics and analog RF-over-fiber links.
Key Features
- OS2 single-mode 9/125µm fiber supports 10G/40G/100G Ethernet and coherent 400G optics
- SC to LC/APC connectors: SC simplex on one end, LC simplex APC (angled) on the other
- 1.6mm simplex cable body fits high-density patch panels and tight bend-radius troughs
- Riser-rated (OFNR) yellow jacket for vertical cable runs in commercial buildings
- 10-meter (32.81 ft) length handles adjacent-rack cross-connects and horizontal patch fields
- Standard insertion loss specification ensures <0.5 dB typical loss per mated pair
- Standard polarity (key-up to key-up) eliminates A/B cable confusion in structured deployments
- EN 60332-1-2 flame-test certified for international datacenter compliance
Single-mode OS2 fiber operates at 9µm core diameter and supports wavelengths from 1260 nm to 1625 nm, making this patch cord compatible with 10GBASE-LR/ER/ZR SFP+ transceivers, 40GBASE-LR4 QSFP+ modules, 100GBASE-LR4/ER4 optics, and emerging 400G coherent interfaces. The LC/APC connector uses an 8° angled polish to direct reflected light into the cladding rather than back toward the source—reducing return loss below -60 dB and preventing laser instability in DWDM systems, CATV distribution, and precision test setups. SC connectors remain the workhorse for ODF terminations, legacy SAN storage, and telco demarcation points; this hybrid SC-to-LC construction bridges older SC-equipped switches or storage arrays to modern LC-dominated 10G/25G/100G switch fabrics without requiring costly adapter panels. The 1.6mm cable diameter uses a tight-buffered 900µm fiber inside a thermoplastic jacket, yielding a bend radius as low as 10× cable diameter (16mm) under no-load conditions—half the radius of 3mm zipcord—so you can route through shallow U-space troughs and around densely populated patch-panel frames without risking macrobend attenuation spikes.
Deploy this patch cord in datacenter top-of-rack to end-of-row aggregation links, SAN fabric connections between blade enclosures and FC switches, campus fiber horizontals from IDF to desktop media converters, or A/V facility ties between SDI routers and fiber-optic extenders. The riser (OFNR) flammability rating satisfies NEC Article 770 for vertical pathways in non-plenum spaces—install it in riser shafts, equipment rooms, and above drop-ceiling grid systems without requiring plenum-grade cable, saving cost where air-handling spaces aren't involved. The 10-meter length suits same-row or adjacent-row equipment connections: two racks 15 feet apart with overhead cable tray leave enough slack for service loops and future moves. Standard polarity means both connectors follow the same key orientation (transmit-to-receive mapping handled by transceiver, not cable crossover), so technicians don't need to track A-side versus B-side patch cords during MAC work. Panduit ships these in cartons of 10, each individually bagged with protective dust caps on both connectors; the UPC 61305680468 ties directly to procurement systems for inventory tracking.
Manufactured to TIA-568-C.3 and IEC 61754 connector geometry standards, each patch cord undergoes factory insertion-loss and return-loss testing before shipment—expect <0.3 dB insertion loss on the LC/APC mated pair and <0.5 dB on the SC pair under typical conditions. The yellow jacket color aligns with TIA-598-C single-mode cable identification conventions, reducing cross-connection errors in mixed multimode/single-mode environments. For integrators managing structured cabling at scale, Panduit's Opti-Core line delivers batch-to-batch consistency in polish quality and cable mechanics, cutting troubleshooting time when a link budget comes in 0.2 dB higher than calculated—you know the patch cord isn't the variable.
